THREE NEW: new media (waterproof wear corrosion), new structures (rigid folded filter arrangement, no steel skeleton, no media wear and tear), a new theory (instead of deep filter surface of the filter dust, no penetration and filter internal material). Cleaning formula used for years, behind the air box pulse dust blowing, mechanical rapping crew, have already been eliminated by the National United States, Germany, Australia and so on. It is these old cartridge filter dust generation product, its advantages are as follows: 1) The surface of the filter cartridge filter collection efficiency is much higher than the old filter, greatly reducing the emissions of harmful substances, air purification indicators have reached the world advanced level, completely changed the old dust is mainly the backward state. 2) Filter cartridge filter without wear and tear, the body which has no moving parts, long-term use is not required to repair (even removable cartridge is also very convenient) to avoid the old-fashioned dust constantly changing media troubles, province money saving time nor secondary pollution. 3) Cartridge filter its size, weight is far less than the old filter with the specifications, save construction space and civil load, saving significant infrastructure investment. 4) Cartridge collector resistance, a small amount of compressed air consumption, no maintenance workload. Various types of dust than the old energy, owned more than 30%, any enterprise can not ignore the energy savings to the enterprise significant economic benefits. ? 2.Bag filter of the advantages: 1) It is simple, continuous cleaning, resistance stability, high filtration speed, no internal moving parts, simple design and other characteristics, is a high performance bag filter. High 2) Removal efficiency can trap more dust 0.3UM so dusty gas purification to 15mg / m3 or less. 3) Less ancillary equipment, investment, technical requirements are not high for filter bags. 4)Capturing electrostatic precipitator dust is difficult to recover, and to some extent, nitrites, sulfides and other compounds can be collected. 5) Changes in load adaptability, especially suitable trapping fine dry dust, collect dry dust to facilitate the handling and recycling. 6) Baghouse collection containing explosive or dusty gas with a spark higher security. 3. Bag filter Disadvantages: 1) For different types of gas, you should use the appropriate type of bag, and the need for frequent replacement bag, bag consumption is large. 2) The collection of high humidity dust gas, moisture should take measures so as to avoid condensation caused by “paste bag”, so baghouse gas humidity have certain requirements. 3) Greater resistance, general pressure loss 1000-1500 PA. 4) For the high-temperature gas, cooling measures must be used. 5) Receives a large particle diameter of dusty gas, bag easier to wear.
